1.主鏈型polybenzoxazine的前驅物P(B-bapf)是以9,9''-bis(4-aminophenyl)fluorene(Bapf)、Bisphenol A(BPA)與formaldehyde進行Mannich縮合聚合反應合成出來。縮合聚合的溶劑效應先前已檢視過,我們發現在眾多溶劑中,以Toluene/Ethanol為溶劑製備出的polybenzoxazine前驅物有最好的純度以及較高的分子量。我們將探討P(B-bapf)與dicyanate ester of bisphenol A (BACY)混合後固化的熱性質與介電性質,並以DSC和IR追蹤並探討其混合後的固化反應。混合後的性質也會作一系列探討。
pOH-Bz與F-a(以bisphenol A/aniline/formaldehyde合成的

1.A main-chain type polybenzoxazine precursor, P(B-bapf) was synthesized from the Mannich-type polycondensation of 9,9-bis(4-aminophenyl)fluorene (Bapf), bisphenol A(BPA), and formaldehyde. The solvent effect on the polycondensation was examined. We found that polybenzoxazine precursor prepared in toluene/ethanol exhibit the best purity and higher molecular weight, among the solvents we have tried. We investigated the curing behaviors, thermal and dielectric properties of the blends of P(B-bapf) and dicyanate ester of bisphenol A(BACY). DSC and IR were applied to monitor the curing reactions of the reactive blends, and the reactions in the reactive blends were discussed. The properties of the blend were also investigated.
2.Phenolic OH-containing benzoxazine (p-OHBz), which cannot be easily prepared by traditional procedures, have successfully been prepared. p-OHBz was prepared from the condensation of 4-aminophenol and 5,5''-methylenebis(2-hydroxybenzaldehyde), reducing the resulting imine linkage by NaBH4, and ring closure condensation. The key starting material, 5,5''-methylenebis(2-hydroxybenzaldehyde), was prepared from 2-hydroxybenzodehyde and s-trioxane in the presence of sulfuric acid. p-OHBz is structurally similar to bis(3,4-dihydro-2H-3-phenyl-1,3-benzoxazinyl)methane (F-a, a benzoxizne based on bisphenol F/aniline/formaldehyde) except for the two phenolic OHs. The phenolic OHs can provide a reaction site with epoxy and 1,1''-(methylenedi-p-phenylene)bismaleimide (DDM-BMI). The structure-property relationships between p-OHBz/epoxy, F-a/epoxy, p-OHBz/DDM-BMI, F-a/DDM-BMI copolymers were discussed.
